Web Host Upload Limitations - Product Download Encryption Needed Offline

[terrytoledo]

PROBLEM:
My client's web hosting is on a shared server
The maximum file size that his php can handle is around 50MB
He wants to sell digital video downloads of files closer to 150MB

DESIRED SOLUTION:
Prestashop module that encodes a product for download and saves this large file OFFLINE
My client uploads this encrypted file via FTP to prestashop's download directory
My client is willing to pay for this module, please provide a quote

ACCEPTABLE SOLUTION:
My client uploads a temporary text file when creating a new product for download
I learn how to encrypt product download files using some kind of application
I upload the large encrypted file via FTP, replacing the temporary file

FAILED SOLUTION: I have created a product for download, used a file under 5MB to upload via the prestashop PHP process. I then uploaded the large file via FTP. I deleted the small file, and changed the name of the large file to match the deleted, small file. After the product was purchased the download link leads to this message, "This file no more exists."

- this post suggests removing the security hash from the file upload process, leaving the file unencrypted? I have not tried this, the thread has not concluded this issue "solved". Is encryption important? Are the files still protected by their location in the download directory?

- this post suggests forcing the php to upload the file directly, bypassing the memory and editing the php.ini file. Although I have tried this solution, my attempts to upload files over 50MB have timed out.

I'm in the file testing stages of a module to let you upload files via ftp, and assign them products (making those products downloadable).

It should be on my store in the next couple of days.
